Apple and Cisco lend support to Microsoft in cloud data access debate

Firms come together to question wisdom of recent ruling from US judge

Apple and Cisco have voiced their support for Microsoft in its battle with US authorities over the right to access cloud data stored overseas. The Electronic Frontier Foundation (EFF), Verizon and AT&T have added their support too.

"We're continuing to challenge this search warrant in the courts as promised on behalf of our customers who expect and deserve basic privacy rights," Microsoft said.

"The US government can't execute a search warrant in other countries, and we don't believe it has the authority to ask Microsoft to do what it can't."

Now, in a court document filed on Friday, legal counsels for Cisco and Apple filed a joint document adding their support for Microsoft's position.

"The Magistrate’s failure to include a more thorough international law and comity analysis has serious consequences and, if followed by other courts, is likely to put Apple and other providers in the untenable situation of being forced to violate one nation’s laws to comply with another," the document reads.

Microsoft will no doubt welcome the support from two other leading tech giants, and the fact Apple especially is willing to lend its public support to a rival's legal fight underlines the strength of feeling the situation is generating.

The EFF also confirmed its support for Microsoft on its website, saying that such a warrant would be against local rights and bad for the industry.

"The magistrate's decision in this case allowed the US government to use a warrant to compel Microsoft to produce a customer's email stored overseas. Verizon believes that decision was wrong: the law does not allow the US government to use a search warrant to obtain customer data stored overseas," he wrote.

"We think the decision was wrong when applied to an email service provider; it would be even more wrong to apply the same logic to customers' data stored in cloud data centers outside the US."

The case could well prove to be a landmark moment in the cloud industry as the outcome of the legal case will pose serious questions for firms wary of the possibility US authorities could seize their data at any point, even if stored overseas.
